The MEncoder shipped with PMS 1.30.1 was compiled for OSX 10.6 and OSX 10.5. But not for OSX 10.4! You could try much older versions of MEncoder, e.g. mencoder from r329.To download it, save the link under "view raw file" as "mencoder".

I think you can still run the latest version of PMS without uninstalling anything. Just replace the modern binaries in "/Applications/PS3 Media Server.app/Contents/Resources/Java/osx/" with their older counterparts. You can find these by browsing the file history in the trunk.

Raptor399 ,thanks for the advice I have some of the files working with 1.40 now but I can still can't play mkv's. I replaced the mencoder (r329), mplayer (r329), flac (r315) , and ffmpeg (r329) . I did not replace tsMuxer and dcraw due because they hasn't been any revisions to those files. I changed the permissions of those files to make them executable and placed them in the package directory and then restarted PMS. I attmpted to play an mkv and it was corrupted. Debug below.

Looks like it works very well for you!Well, except for that tsMuxeR error, that is.

To see what that error is, you can install PMS 1.50-b2 and look at that logfile.That version is more verbose in its error messages in the logfile and it might tell you why exactly tsMuxeR is refusing to run.
